Mark 2:16-18

16And the scribes of the Pharisees, when they saw that he was eating with sinners and tax collectors, said to his disciples, "Why does he eat with tax collectors and sinners?"

17And when Jesus heard it, he said to them, "Those who are well have no need of a physician, but those who are sick. I came not to call the righteous, but sinners."

18Now John's disciples and the Pharisees were fasting. And people came and said to him, "Why do John's disciples and the disciples of the Pharisees fast, but your disciples do not fast?"
